The C-clip can only be used in pistons with a slot in the side of the pisten, with older pistons without a slot it is very difficult to remove them.
Otherwise you can use the G-clipin pistons with a C-clip.
The extra material on the G-clip is weight and can create a lot of G-force on hugh RPM, even that much the clip can loosen itself.
